Test Case Assigment at Test Plan Level

[WT1]

With the release of 1.9 beta6 a feature was added to allow the user to test cases at the build level. However this feature does seem to effect the excising assignments as the note below from the install process indicates.

"TestLink version 1.9 uses a new method of assigning users to test cases. This assignment is now done on build level instead of only test plan level like it was in older versions. Because of this change, your existing user assignments will be modified during migration:
For every test plan, all existing assignments of users to test cases will be deleted and re-assigned only to the newest found build in this test plan.
You will of course have the chance to change these assignments manually in TestLink after migration. When you create a new build, existing assignments from a selected existing build can also be copied directly on creation of the new build."

This leaves me with a question. Am I reading this correctly in that all previous assignments for every pass build will be lost , but will be re-assigned to the newest build? Also going forward all test case assignments are associated with both a plan and a build, is that a correct statement?

I am trying to get a better picture of what will happen when I do the install and upgrade from my current setup to 1.9 as far as assignments go.
